Gearbox bench procedures consist of removal and replacement procedures of all gearbox com-
ponents (with the exception of pump shafts and gear ratios). Gearbox bench procedures are
identical for all four Flex series single stage pumps once the pump has been removed from the
gearbox. All of the subparagraphs in this section (bench procedures) provide removal and re-
placement procedures for selected Gearbox components and apply to all four booster pumps.
Figure 24 and Figure 25 show exploded views of the Gearbox.
When the bench procedure(s) is (are) completed, the pump portion (assemblies) must be rein-
stalled on the gearbox before the unit can be reinstalled on the apparatus. Use the General
Gearbox Installation portion of paragraph 5.9.1 to install the pump assemblies onto the gearbox.
After assembling the pump to the gearbox reinstall the unit on the apparatus, use para-
graph 5.8.8 for instructions to reinstall the unit on the apparatus.

This procedure requires gearbox removal prior to performance to provide input shaft access. See
